I think d basic instinct of human is like animals, its our brain which makes us different n civilised frm all other animals. We sud use it in d right path - now its the matter of debate what is d right path. There is no harm in having sexual fantasies but of course using it dat way n in public places remind me of the month of KARTIK when many of d streets of Nepal r full of dog scenes- i think everyone got it........human beings r different dan dogs i guess.
